E. n. MoRRIsoN, or BROOKLYN. NEW vonk,` AssIGNoR rro s. o. Hints. orisaMiii j f sHINGLEavLAcHINE.

Be it known that I, E. R. MoRrJsoN, `of Brooklyn, in the county ofrKings and State of New York, have invented a new and Improved Shingle-Machine; and I do hereby declare that `the Afollowing is a full, clear, and exact description of the same, Areference being had to the annexed drawings, making a part of `this specification, in whichu Figures `l and 2, are side sectional views of my invention taken in theline onFigs. 3 and 4. Fig 3, is a transverse section of ditto, taken in the line ly, y, Fig. l. Fig. 1l,

is a plan or top view of ditto. j p

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to an improvement in that class of shingle machinesin which the shingle is rived from the bolt withparallel sides andthen planed or shaved in proper taper form. i

The object ofthe within described invention is to obtain a simple machine for `the intended purpose and one that maybe very readily manipulated by a person of ordinary To enable those skilled in the artto fully understand and construct my invention I will proceed to describe it.

A, A, `represents two parallel bars whichV are connected by suitable cross bars a, and which are increased in depth at one end to be of suitable dimensions `tofreceive sides B, B, the ends of which are fitted and work in grooves b, b, in the inner surfaces of the bars A, at right angles with each other, see Figs. 1 and 2.

To the inner end of each slide B, B, a planer or knife C, is attached, the knives extending the whole width of the slides and secured thereto by screws or bolts. In the outer part of each slide B, and at their inner sides, plates D, are connected byteeth c, which t in corresponding recesses in the slides and form what may be termed a gear attachment which will be fully understood by referring to Figs. l and 2. The plates D, are provided with journals d, at `their inner ends, said journals having their bearings in the bars A, A, and the journals of one plate being directly over and in the same plane with those of the other. The journals d, at

` one end extend through their bar A, and are connected by a toothed or geared portion e, as shown clearly bythe dotted lines in Figs.` 1 and 2.

E,1is attachedysaid blml `being parallel with j To the uppermost.gearedjournalthiabarl the bars A, A, and fhaving itsouterjend provided with a forked pin j. f,which iisiitted on a cleator ledgelFyformedof an inclined and horizontal 1portion g, it, as shown by j i dotted linesin Figs; l` ;and2,.and attached j f to one side of Aa bedG, whichis fittedon`- dove-tail guides or ways fi, ki, @on y the bars A, A. l On the cross tagfa,oflae` angetan@ n;

bars A, A, ,slats jare attached, said slats-lbe-` l ing parallel withthegbars A, lA,as shown clearly in Fig. 4f.

. The bedG, is formed `oftwo..parallel bars 1 l 7c, k, connected at their outer endjby a ltravf alf erse barl, and having a boardor :Eplate fm1, fitted between whichboardqor jplatefisate` tached to the barfjl, enly lof the bed, so

to allow the inner end ofthe board or` plate` j to yield `or. give to `a ,certa-inextent.;` To@ the under side ofthefinner part of thejplate or board m, pendants@ are attached, jthe lower parts of `whichjat `their inner sides are inclined, as .j ShOWll" Clearly `in Figs.

and 2. The pendants a, extend down directlyover and between thegspaces between the slats j. On the innerpartofthe `upper i surface of the boardorj `plate,mgarlving"` "i knife H, is secured.` "This knife gis `si a steellplate having afcuttingedge forme l" by a basil `at under side, asjshown in l Figs. land 2. The plateorboardjm, at-its `inner part and atitsupperfsurface is`re u `cessed longitudinallylfora short distance` asshownato-` .p p j Directly over the lbed G, a transverse bearing-piece I, fis placed.` This bearing` piece may be formed lof. two transverse barsp, p, attached to uprights r, r, secured to 3 the bars A, A. The bar p, is provided with "1 journals `at its end, `and they are allowed to rock in theirbearingsm To the bar p, a" i C plate s, is attached, which plateeirtends` the whole width of the plate er1/,zand has projec-` ,3 "y

tions t, at its under side which register with the recesses 0, in plate m. C -I The inner end of theknifeI-I, projectsa trifle beyond the `inner end of the 1bed G, and to one of the uprights i', a spring or yielding bar u, is attached, having a hori ica` zontal projection fu, at its `inner end` which` extends over the end "ofpthe bed G, j.

I', represents a plate,`theiends of which are attached to bars Mrz', that are secured," L

oneto each bar A.` To" one ofthe barsafp" `1 a Spring b', is attached, said springs hav- `ing a tendency to keep the plate I, down toward the slats j.

` The operation is as follows: The device is attached in an inclined position to any suitable framing, see Fig. 3, and a reciprocating movement is given the bed G, in any proper way. The operator stands by the side of the machine and the bolt, shown in red, is previously got out of proper dimensions and is placed on the bed G, between the bearing-piece I, and the knife H. As the bed Gr, moves outward in the direction of arrow 1, the lmife H, rives a shingle from the lower part of the bolt, the bearing-piece I, retains the bolt while it is acted upon by the knife. The knife I-I, passes over the plate 1, and the latter consequently insures a complete cut of the knife and a proper discharge of the shingle on the slats j, the bolt being Vretained when the bed has reached the termination of its outward stroke by the outer part of the knife H, and the projection o, see Fig. 2. On the return movelnent of the bed Gr, as indicated by the arrow 2, the shingle on the slats j, is shoved by the pendants n, under the plate I, and between the planers or knives C, C, which as the shingle enters the space between them are distended the full length of their movement by the plates D, D, and bar E, which are actuated by the ledge or projection F, at the side of the bed Gr. The knives C, C, are kept distended a certain length of time, as the bed moves in the direction of arrow 2, in consequence of the horizontal portion z., of the ledge or projection F, and by this means the shingles are shaved or planedwith parallel upper and lower surfaces for a short distance near the butt, and are then planed in taper form in consequence of the inclined portion g, of the ledge actuating the bar' F. The inclined surfaces of the pendants n, have a tendency to keep the shingle down on the slats j, as the bed G, moves in the direction of arrow 2, and the plate I', also presses on the shingle. As the bed G, approaches the termination of its inner stroke or movement indicated by arrow 2, the plate I, is raised and the nished shingle drops by its own gravity aided by the inclination of the machine. The bed Gr, as it passes underneath the bolt throws out the projection o, and the bolt passes or falls on the plate m, ready for a succeeding cut as the bed moves outward in the direction of arrow l. The yielding bottom plate or board m, compensates for any winding or irregularity of the grain of the bolt and thereby prevents any binding tendency during the operation of the knife I-I. The projection v, as the bed G, moves outward is forced inward by the elasticity of the bar u, so as to be in proper position to sustain the bolt when the succeeding shingle is cut from it.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is-

1. The arrangement of the knife I-I, and projection v, in connection with the reciprocating bed substantially as shown whereby the bolt'is supported as the bed passes underneath it during the cutting or riving operation.

2. The employment o'r use of the planers or Vknives C, C, operated by the plates D, D, bar E, and ledge or projection F, on the bed Gr, substantially as and for the purpose described.
